3 / 10 page 74V1T77 3/10 DC SPECIFICATIONS AC ELECTRICAL CHARACTERISTICS (Input tr = tf = 3ns) (*) Voltage range is 5.0V ± 0.5V CAPACITIVE CHARACTERISTICS 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC Symbol Parameter Test Condition Value Unit VCC (V) TA = 25°C -40 to 85°C -55 to 125°C Min. Typ. Max. Min. Max. Min. Max.
